Blake Shelton Freaks Out Over Gwen Stefani on the Empire State Building

Gwen Stefani has received quite an honor that Blake Shelton simply cannot top. The Voice coach and pop superstar's photo Harper's Bazaar shoot is displayed on the Empire State Building in honor or the publication's 150th anniversary.

The image was featured on the cover in 2012.

Shelton is clearly proud of his girlfriend, writing on Instagram on Thursday (April 20): "Ok..To whomever put my girlfriends picture on the Empire State Building thanks a lot....How can I top that sh--?!!"

The historic building displays a gorgeous photo of Stefani looking fierce at the camera while donning a chic pink hat in the shape of a giant rose. The No Doubt singer also shared the shot on her own Instagram page with the caption "#crazy!"

Other notable figures who've had the honor of being projected on to the Empire State building include Jennifer Lopez, Lady Gaga and Jennifer Anniston.

Shelton and Stefani are currently serving on the coaching panel on Season 12 of The Voice. The two began dating after meeting on the reality show in 2015 and made their public debut as a couple at the 2015 CMA Awards. It's no shock that Stefani adores the country singer, but apparently her children do as well.

"They’re just into him … who isn’t?We always have fun together, it’s a blast," she tells Extra about her sons' admiration for the country star. She has three boys, 10-year-old Kingston, 8-year-old Zuma and 3-year-old Apollo, with her ex-husband.

Shelton is up for two Billboard Music Awards in 2017 for Top Country Artist and Top Country Album with If I'm Honest, which picked up a 2017 People's Choice Award for Favorite Album, the first time a country star has ever won the all-genre category.
